NHSA Module 3 Practice Test

Protecting the people inside the vehicle is the priority. The passenger compartment is the area where occupants sit, and it’s designed to stay intact and maintain a survivable space during a crash. Keeping this space secure helps reduce injury by shielding riders from intrusion and absorbing some crash energy. The engine block, radiator, and cargo area aren’t built to provide the same level of protection for occupants; they’re part of the vehicle’s mechanical function or storage, and they don’t serve as the primary safe space for people in a collision.
